This paper explores the vital role of code-switching strategies in English language teaching within applied undergraduate universities, focusing on the context of an increasingly globalized world where proficiency in English has become essential for academic success and future employability. As globalization intensifies, the demand for skilled English speakers is growing, further amplifying the significance of effective English language education. In this landscape, code-switching—often perceived negatively in traditional linguistic frameworks—emerges as a powerful pedagogical tool that can promote comprehension, engagement, and overall proficiency among students. This study delves into the theoretical underpinnings of code-switching, examining its roots in sociolinguistics and its implications for language acquisition. Specifically, it highlights how strategic code-switching allows educators to bridge the gap between students’ native languages and the target language, fostering a richer, more inclusive learning environment. Through an empirical of classroom practices, the paper captures diverse stakeholder responses, including students’ perceptions of code-switching as a supportive mechanism in their learning process and educators’ attitudes towards its integration into teaching methodologies. Furthermore, the study discusses the practical applications of code-switching strategies, offering insights into how educators can effectively implement these techniques to improve instructional effectiveness and student outcomes. The findings underscore the need for professional development programs that equip teachers with the skills to utilize code-switching strategically, thus paving the way for a more culturally responsive pedagogy. By addressing both theoretical and practical dimensions, this paper aims to enrich the understanding of code-switching in English language teaching and advocate for its recognized value as an essential component of modern pedagogical practices.
